LEAD IN PETROL - METHODS OF REDUCTION

BLY I BENSIN - MOEJLGHETER TILL BEGRAENSNINGAR

The Swedish parliament of 1968 directed that steps must be taken to reduce the lead content of petrol. From 1.1.1970 the limit was 0.70 g/litre, and from 1.1.1973, 0.4 g/litre. Further reduction to 0.15 g/l is planned. Reduction of benzene content to 5% by volume is also planned. There is A discussion of additives, engine design and refining processes. The only way to reduce pollution due to lead is reduction at source, as construction and disposal of efficient filters appears too difficult and too expensive. Production of low-lead petrol of the same octane rating would increase petrol prices by about skr 0.03 per litre. If a change is made in Sweden to production of low-lead petrol, Swedish refineries would need to be equipped with isomerisation plant. This can be done in 1 1/2 years. One way of reducing environmental effects to some extent may be to lower the lead content of regular petrol only, which however accounts only for about 40% of consumption in Sweden, and to restrict this low-lead petrol to the three metropolitan areas which together account for 30-40% of total petrol consumption. /TRRL/
